I do think it's an exotic request, and the reason is that it's not in
APT's responsibilities.
Apt should manage software installation and removal, which it does based
on your installed packages, and your *current* repositories. What you're
asking needs information also on *past* repositories.
Lets look at unstable, in which packages come and go relatively quick.
It mean, that if I don't update daily, I can find myself with installed
packages which currently doesn't exist in the repository. From where
should apt take the info about the source repository?
I think I was not clear enough on my question.
I don't ask apt to store history of "download source of package", all
I'm asking is that with the current state, when all repositories are
configured in sources.list to get a reply from apt that if I ask for
package X he will wget it from http://heaven.org/angel.deb.
To follow your example for unstable: I don't care for updates. You
have your local copy(s) of Packages.gz please tell me what package you
choosed (after you ran you algorithms.cc) and from what repository
will you be fetching it, that's all I'm asking.
On a more technical side:
When you create a package, you do that regardless of any repository, so
there isn't any meta data about that. Before installation APT (and
aptitude) will resolve the package dependencies and download the .deb
files. From there, the installation is done with DPKG, which doesn't
know anything about repositories. Same as you would have done the
installation manually with DPKG.
I hope this answer is enough. Please let me know if you want more info.

$ apt-cache show libapt-pkg-doc

Description: Documentation for APT development
This package contains documentation for development of the APT
Debian package manipulation program and its libraries.
From a quick play with python-apt, it seems that apt will not report
this info to the upper layer. Pasting from apt source
apt-pkg/pkgrecords.h pkgRecords does not have such field:
"""
class pkgRecords::Parser
{
protected:
virtual bool Jump(pkgCache::VerFileIterator const &Ver) = 0;
public:
friend class pkgRecords;
// These refer to the archive file for the Version
virtual string FileName() {return string();};
virtual string MD5Hash() {return string();};
virtual string SHA1Hash() {return string();};
virtual string SourcePkg() {return string();};
// These are some general stats about the package
virtual string Maintainer() {return string();};
virtual string ShortDesc() {return string();};
virtual string LongDesc() {return string();};
virtual string Name() {return string();};
// The record in binary form
virtual void GetRec(const char *&Start,const char *&Stop) {Start =
Stop = 0;};
virtual ~Parser() {};
};
"""
The Ubuntu upgrade is almost over here, I don't think I will be
pursuing this issue any further.
Thank you for the answers Lior.
Enjoy.
You too, and keep up the great work.
